This study aimed to evaluate the efficacy and safety of bronchoscopic cryoablation combined with sintilimab plus platinum-based chemotherapy as First-line Treatment for locally advanced or metastatic NSCLC with central airway obstruction.
Understand the requirements and contents of the clinical trial and provide a signed and dated informed consent form.
Age≥18 years and≤80 years.
Histologically or cytologically confirmed and documented locally advanced or metastatic non-small cell lung cancer (NSCLC) without prior systemic therapy and EGFR-sensitive mutations (19del, L858R and T790M).
Presence of a palliative treatment lesion in the central airway that is amenable to ablation, endoscopically assessed to be≥1/3 obstruction, such as primary or metastatic malignancy to the trachea, main bronchi, intermediate bronchi, or segmental bronchi. corresponding respiratory symptoms or obstructive pneumonia is permission to be included.
Histological diagnosis of small cell, large cell lung cancer; mixed tumors will be classified based on the primary cell type; if the primary component is small cell, large cell, or neuroendocrine carcinoma, the subject will not be eligible for enrollment; however, mixed adenocarcinoma-squamous cell carcinoma is acceptable. Subjects with driver gene mutations are generally not eligible for enrollment.
Malignant central airway obstruction with acute dyspnea or severe life-threatening symptoms of malignant airway stenosis, or assessed by the investigator to be unable to tolerate subsequent treatment; extrinsic airway compression; large pleural effusion, severe coughing, massive hemoptysis, dyspnea, or inability to cooperate; severely impaired lung function with a maximal voluntary ventilation (MVV) < 39% or inability to ambulate.
Prior systemic therapy for locally or metastatic disease.
Uncorrectable coagulation disorders, severe bleeding tendencies, platelet count < 50 *10^9/L, or severe coagulation dysfunction.
